Detailed Implementation

[0079] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0080] With the development of communication technology, the power of antenna components has gradually increased to improve signal transmission quality. Since users may interact with electronic devices during communication, higher power can negatively impact their health, necessitating the detection of electromagnetic wave absorption ratios to adjust the antenna component's power. Because of this absorption ratio detection requirement, the antenna component incorporates a floating frame segment, which does not include a grounding point. During signal transmission, interference signals can arise from either the floating frame segment transmitting to the frame segments on either side, or vice versa, leading to poor antenna component performance.

[0081] Based on this, the present disclosure provides an antenna assembly that, through tuning by a tuning circuit electrically connected to both the first and second frame segments, can eliminate interference signals generated by the suspended frame segment to the frame segments on both sides or interference signals generated by the frame segments on both sides to the suspended frame segment, thereby improving the performance of the antenna assembly.

[0082] An exemplary embodiment of this disclosure provides an antenna assembly, such as Figure 1 As shown, the antenna assembly includes a conductive frame 10, multiple tuning circuits 20, and multiple matching circuits 30. The conductive frame 10 includes a first frame segment 11 and a second frame segment 12. The first frame segment 11 is disposed on at least one side of the second frame segment 12, and a gap exists between the first frame segment 11 and the second frame segment 12. The second frame segment 12 is a suspended frame segment, and both the first frame segment 11 and the second frame segment 12 constitute antenna radiators. Partial tuning circuits 20 are electrically connected to the first frame segment 11, and partial tuning circuits 20 are electrically connected to the second frame segment 12. Partial matching circuits 30 are electrically connected between the first frame segment 11 and at least one first signal source 40, and partial matching circuits 30 are electrically connected between the second frame segment 12 and at least one second signal source 50.

[0083] In this embodiment, the antenna assembly includes a conductive frame, multiple tuning circuits, and multiple matching circuits. The tuning circuits are electrically connected to corresponding first and / or second frame segments within the conductive frame, and the matching circuits are electrically connected to corresponding first or second frame segments. Because the tuning circuits are electrically connected to both the first and second frame segments, tuning can be performed while meeting the electromagnetic wave absorption ratio detection requirements to eliminate interference signals from the floating frame segments, thereby improving the performance of the antenna assembly.

[0084] In one embodiment, such as Figure 2 As shown, the second frame segment 12 constitutes the first antenna radiator, and the portion between the two ends of the first antenna radiator constitutes the first radiating branch 121 of the first antenna radiator.

[0085] In this embodiment, the portion between the two ends of the first antenna radiator forms a first radiating stub. Under the tuning of the tuning circuit, the operating frequency band of the first radiating stub can cover multiple different low-frequency bands. By using a second frame segment to form the first radiating stub to transmit signals of multiple low-frequency bands, the occupancy of the frame segment can be reduced while meeting the electromagnetic wave absorption ratio detection requirements, thereby reducing the complexity of the antenna assembly structure.

[0086] In one embodiment, the first frame segment 11 disposed on one side of the second frame segment 12 constitutes the second antenna radiator. The portion of the second antenna radiator between the end of the second antenna radiator near the first antenna radiator and the grounding point of the second antenna radiator constitutes the second radiation branch 111 of the second antenna radiator. The portion of the second antenna radiator between the end of the second antenna radiator near the first antenna radiator and the first feed point of the second antenna radiator constitutes the third radiation branch 112 of the second antenna radiator. The portion of the second antenna radiator between the end of the second antenna radiator near the first antenna radiator and the second feed point of the second antenna radiator constitutes the fourth radiation branch 113 of the second antenna radiator.

[0087] In this embodiment, a second radiating stub is formed by the portion between the end of the second antenna radiator closest to the first antenna radiator and the grounding point of the second antenna radiator. The operating frequency band of the second radiating stub can cover one frequency band. A third radiating stub is formed by the portion between the end of the second antenna radiator closest to the first antenna radiator and the first feed point of the second antenna radiator. The operating frequency band of the third radiating stub can cover one frequency band. A fourth radiating stub is formed by the portion between the end of the second antenna radiator closest to the first antenna radiator and the second feed point of the second antenna radiator. The operating frequency band of the fourth radiating stub can cover one frequency band. By reusing a first frame segment to form three radiating stubs, interference between signals of different frequency bands can be prevented while reducing the frame segment occupancy, thereby improving the performance of the antenna assembly.

[0088] In one embodiment, the first frame segment 11 disposed on the other side of the second frame segment 12 constitutes the third antenna radiator. The portion of the third antenna radiator between the end of the third antenna radiator near the first antenna radiator and the third feed point of the third antenna radiator constitutes the fifth radiating branch 114 of the third antenna radiator. The portion of the third antenna radiator between the end of the third antenna radiator near the first antenna radiator and the ground point of the third antenna radiator constitutes the sixth radiating branch 115 of the third antenna radiator.

[0089] In this embodiment, a fifth radiating stub is formed by the portion between the end of the third antenna radiator closest to the first antenna radiator and the third feed point of the third antenna radiator. The operating frequency band of the fifth radiating stub can cover multiple frequency bands. A sixth radiating stub is formed by the portion between the end of the third antenna radiator closest to the first antenna radiator and the ground point of the third antenna radiator. The operating frequency band of the sixth radiating stub can also cover multiple frequency bands. By reusing a first frame segment to form two radiating stubs, interference between signals of different frequency bands can be prevented while reducing the frame segment occupancy, thereby improving the performance of the antenna assembly.

[0090] For example, when a user holds and uses the electronic device, the second frame segment 12 may be located on the upper side of the electronic device, one first frame segment 11 may be located on the left side of the second frame segment 12, and another first frame segment 11 may be located on the right side of the second frame segment 12.

[0091] In one embodiment, the length l1 of the first radiating branch 121 is 26mm-32mm, the length l2 of the second radiating branch 111 is 14mm-20mm, the length l3 of the third radiating branch 112 is 4mm-10mm, the length l4 of the fourth radiating branch 113 is 1mm-3mm, the length l5 of the fifth radiating branch 114 is 3mm-7mm, and the length l6 of the sixth radiating branch 115 is 12mm-18mm.

[0092] In this embodiment, by setting the length of the first radiating stub to 26mm-32mm, the signal transmission quality can be improved by tuning the tuning circuit for different low-frequency signals, while minimizing the impact of the signal transmitted by the first radiating stub on the user. By setting the length of the second radiating stub to 14mm-20mm, the quality of low-frequency signal transmission can be improved, while minimizing the impact of the signal transmitted by the second radiating stub on the user. By setting the length of the third radiating stub to 4mm-10mm, the quality of low-frequency signal transmission can be improved, while minimizing the impact of the signal transmitted by the third radiating stub on the user. By setting the length of the fourth radiating stub to 1mm-3mm, the quality of high-frequency signal transmission can be improved, while minimizing the impact of the signal transmitted by the fourth radiating stub on the user. By setting the length of the fifth radiating stub to 3mm-7mm, the quality of high-frequency signal transmission can be improved, while minimizing the impact of the signal transmitted by the fifth radiating stub on the user. By setting the length of the sixth radiating stub to 12mm-18mm, the quality of mid-frequency signal transmission can be improved, while minimizing the impact of the signal transmitted by the sixth radiating stub on the user. By using the different portions of the first and second frame segments as multiple radiating stubs, the signal transmitted by the antenna assembly is less susceptible to interference, thereby improving the performance of the antenna assembly.

[0093] For example, the length l1 of the first radiating branch 121 is 29 mm, the length l2 of the second radiating branch 111 is 17 mm, the length l3 of the third radiating branch 112 is 7 mm, the length l4 of the fourth radiating branch 113 is 2 mm, the length l5 of the fifth radiating branch 114 is 5 mm, and the length l6 of the sixth radiating branch 115 is 15 mm.

[0094] In one embodiment, the operating frequency band of the first radiating branch 121 includes the transmit (TX) band and receive (RX) band of the BeiDou Navigation Satellite System; the operating frequency band of the second radiating branch 111 includes the L1 band of the Global Positioning System (GPS); the operating frequency band of the third radiating branch 112 includes the 2.4G band of the WIFI (Wireless Fidelity) signal; the operating frequency band of the fourth radiating branch 113 includes the 5G band of the WIFI signal; the operating frequency band of the fifth radiating branch 114 includes the high frequency band; and the operating frequency band of the sixth radiating branch 115 includes the mid frequency band.

[0095] In this embodiment, the first radiating branch is the longest and has a strong ability to transmit low-frequency signals; its operating frequency band includes the transmission and reception bands of the BeiDou Navigation Satellite System. The second radiating branch is also relatively long and has a strong ability to transmit low-frequency signals; its operating frequency band includes the L1 band of the Global Positioning System. The third radiating branch is relatively short and has a moderate ability to transmit mid-to-low frequency signals; its operating frequency band includes the 2.4GHz band of Wi-Fi signals. The fourth radiating branch is the shortest and has the strongest ability to transmit high-frequency signals; its operating frequency band includes the 5GHz band of Wi-Fi signals. The fifth radiating branch is also relatively short and has a strong ability to transmit high-frequency signals; its operating frequency band includes the high-frequency band. The sixth radiating branch is of moderate length and has a strong ability to transmit mid-frequency signals; its operating frequency band includes the mid-frequency band. By transmitting signals of different frequency bands through each radiating stub, the antenna assembly can transmit multi-frequency signals with high signal transmission quality, thereby improving the performance of the antenna assembly.

[0096] For example, under the action of the matching circuit 30, the operating frequency bands of the fifth radiating stub 114 and the sixth radiating stub 115 may include the mid-high frequency band (MHB) and the N78 band.

[0097] In one embodiment, such as Figure 3As shown, the multiple tuning circuits 20 include a first tuning circuit 21 and a second tuning circuit 22. The first tuning circuit 21 has a first terminal electrically connected to the second feed point of the second antenna radiator formed by the first frame segment 11, a second terminal electrically connected to the first tuning point of the first antenna radiator formed by the second frame segment 12, a third terminal electrically connected to the second tuning point of the first antenna radiator, and a fourth terminal electrically connected to a ground point. The second tuning circuit 22 has a first terminal electrically connected to the third tuning point of the first antenna radiator, a second terminal electrically connected to the fourth feed point of the first antenna radiator, and a third terminal electrically connected to a ground point.

[0098] In this embodiment, by electrically connecting the first terminal of the first tuning circuit to the second feed point, interference signals from the second antenna radiator can be eliminated through grounding when the first radiating branch is in operation. By electrically connecting the second terminal of the first tuning circuit to the first tuning point, interference signals from either the first or third antenna radiator can be eliminated through grounding when either the second or third antenna radiator is in operation. By electrically connecting the third terminal of the first tuning circuit to the second tuning point, interference signals from both the first and third antenna radiators can be eliminated through grounding when the second antenna radiator is in operation. By electrically connecting the first terminal of the second tuning circuit to the third tuning point of the first antenna radiator, interference signals from the first antenna radiator can be eliminated through grounding when the third antenna radiator is in operation, thus providing electrical parasitics. By electrically connecting the second terminal of the second tuning circuit to the fourth feed point of the first antenna radiator, the corresponding operating frequency band can be matched through tuning when either the second or third antenna radiator is in operation. By tuning through the first and second tuning circuits, interference signals from the floating frame segment can be eliminated and the corresponding operating frequency band can be matched, thereby improving the performance of the antenna assembly.

[0099] In one embodiment, the distance l7 between the first tuning point and the end of the first antenna radiator near the second antenna radiator is 2mm-5mm, the distance l8 between the second tuning point and the end of the first antenna radiator near the second antenna radiator is 5mm-9mm, the distance l9 between the third tuning point and the end of the first antenna radiator near the third antenna radiator formed by the first frame segment is 5mm-7mm, and the distance l10 between the fourth feed point and the end of the first antenna radiator near the third antenna radiator is 2mm-4mm.

[0100] In this embodiment, because the distance between the first tuning point and the end of the first antenna radiator closest to the second antenna radiator is short, the first tuning circuit can eliminate the interference signal generated by the second antenna radiator from the first antenna radiator through the grounding point, and also eliminate the interference signal generated by the third antenna radiator from the first antenna radiator through the grounding point. Because the distance between the second tuning point and the end of the first antenna radiator closest to the second antenna radiator is long, the first tuning circuit can eliminate the interference signal generated by the first antenna radiator through the grounding point, and also eliminate the interference signal generated by the third antenna radiator from the first antenna radiator through the grounding point. Because the distance between the third tuning point and the end of the first antenna radiator closest to the third antenna radiator is long, the second tuning circuit can eliminate the interference signal generated by the first antenna radiator through the grounding point. Because the distance between the fourth feed point and the end of the first antenna radiator closest to the third antenna radiator is short, the second tuning circuit can match different operating frequency bands of the first antenna radiator and different operating frequency bands of the third antenna radiator through tuning. By setting different tuning points and feed points at different positions on the floating frame segment, interference signals generated by each frame segment can be eliminated and matched to the corresponding operating frequency band, thereby improving the performance of the antenna assembly.

When the first antenna radiator is in operation, the first inductor and the fifth capacitor can match the corresponding operating frequency band. By controlling whether the capacitor, inductor, and resistor are electrically connected to the ground point through a second switching circuit, interference signals can be eliminated and the corresponding operating frequency band can be matched under different operating conditions of the antenna radiator, thereby improving the performance of the antenna assembly.

[0105] In one embodiment, such as Figure 3 As shown, the multiple tuning circuits 20 also include a third tuning circuit 23.

[0114] An exemplary embodiment of this disclosure provides a control method for an antenna assembly, which can be applied, for example, to the antenna assembly described above. Figure 7 As shown, the antenna assembly control method includes:

[0115] S100. Determine the target operating frequency band of the antenna radiator that is in operation.

[0116] S200: Control the tuning circuit to perform tuning according to the target operating frequency band.

[0117] In this embodiment, the target operating frequency band of the antenna radiator in operation is determined to identify the impedance matching the target operating frequency band and the interference signals that need to be eliminated. Based on the target operating frequency band, the tuning circuit is controlled to perform tuning, ensuring reliable signal transmission. By tuning according to the target operating frequency band, energy reflection and loss are reduced, and interference signals from the antenna radiator are eliminated, thereby improving the performance of the antenna assembly.

[0118] In one embodiment, the step S200 of controlling the tuning circuit to perform tuning according to the target operating frequency band can be determined in the following way:

[0119] When the target operating frequency band is the L1 band of the Global Positioning System, the 2.4G band of the WIFI signal, or the 5G band of the WIFI signal, the first switch in the control tuning circuit is turned off, the second switch is turned on, the third switch is turned on, the fourth switch is turned off, the fifth switch is turned off, the sixth switch is turned off, the seventh switch is turned off, the eighth switch is turned off, the ninth switch is turned off, the tenth switch is turned off, and the eleventh switch is turned off.

[0120] In this embodiment, when the target operating frequency band is the L1 band of the Global Positioning System, the 2.4G band of the WIFI signal, or the 5G band of the WIFI signal, the second antenna radiator is in working condition, while the first and third antenna radiators are not in working condition and may generate interference signals. Controlling the first switch to be open, the second switch to be on, and the third switch to be on prevents the signal from the second antenna radiator from being eliminated, and also eliminates the interference signals generated by the first and third antenna radiators. Controlling the fourth, fifth, sixth, seventh, eighth, ninth, tenth, and eleventh switches to be open reduces the interference signals generated by the first and third antenna radiators, and also reduces the power consumption of the second and third tuning circuits. By controlling the corresponding switches in the tuning circuit to be on or off, the interference signals generated by the first and third antenna radiators can be eliminated, thereby improving the performance of the antenna assembly.

[0121] In one embodiment, the step S200 of controlling the tuning circuit to tune according to the target operating frequency band can also be determined in the following way:

[0122] When the target operating frequency band is the transmission frequency band of the BeiDou satellite navigation system, the first switch in the control tuning circuit is turned on, the second switch is turned off, the third switch is turned off, the fourth switch is turned off, the fifth switch is turned off, the sixth switch is turned off, the seventh switch is turned on, the eighth switch is turned off, the ninth switch is turned off, the tenth switch is turned on, and the eleventh switch is turned off.

[0123] When the target operating frequency band is the receiving frequency band of the BeiDou satellite navigation system, control the first switch to be turned on, the second switch to be turned off, the third switch to be turned off, the fourth switch to be turned off, the fifth switch to be turned off, the sixth switch to be turned off, the seventh switch to be turned off, the eighth switch to be turned off, the ninth switch to be turned off, the tenth switch to be turned on, and the eleventh switch to be turned off.

[0124] In this embodiment, when the target operating frequency band is the transmission or reception band of the BeiDou satellite navigation system, the first antenna radiator is in operation, while the second and third antenna radiators are not in operation and may generate interference signals. Controlling the first switch to be on, the second switch to be off, and the third switch to be off eliminates the interference signal generated by the second antenna radiator. Controlling the eighth switch to be off, the ninth switch to be off, the tenth switch to be on, and the eleventh switch to be off eliminates the interference signal generated by the third antenna radiator. Controlling the fourth switch to be off, the fifth switch to be off, and the sixth switch to be off prevents the signal from the first antenna radiator from being eliminated. Controlling the seventh switch to be on or off matches the transmission or reception band of the BeiDou satellite navigation system. By controlling the corresponding switches in the tuning circuit to be on or off, the interference signals generated by the second and third antenna radiators can be eliminated, thereby improving the performance of the antenna assembly.

[0125] In one embodiment, the step S200 of controlling the tuning circuit to perform tuning according to the target operating frequency band can also be determined in the following way:

[0126] When the target operating frequency band is the B3 band of the mid-high frequency band, the first switch in the control tuning circuit is open, the second switch is on, the third switch is open, the fourth switch is on, the fifth switch is on, the sixth switch is open, the seventh switch is open, the eighth switch is open, the ninth switch is open, the tenth switch is open, and the eleventh switch is open.

[0127] When the target operating frequency band is the B3 frequency band in the mid-high frequency band, control the first switch to be off, the second switch to be on, the third switch to be off, the fourth switch to be on, the fifth switch to be on, the sixth switch to be off, the seventh switch to be off, the eighth switch to be off, the ninth switch to be on, the tenth switch to be off, and the eleventh switch to be off.

[0128] When the target operating frequency band is the B1 band in the mid-to-high frequency band, control the first switch to be open, the second switch to be on, the third switch to be open, the fourth switch to be on, the fifth switch to be on, the sixth switch to be open, the seventh switch to be open, the eighth switch to be open, the ninth switch to be open, the tenth switch to be open, and the eleventh switch to be on.

[0129] When the target operating frequency band is the B40 or B41 band in the mid-to-high frequency band, the first switch is turned off, the second switch is turned on, the third switch is turned off, the fourth switch is turned on, the fifth switch is turned on, the sixth switch is turned off, the seventh switch is turned off, the eighth switch is turned on, the ninth switch is turned off, the tenth switch is turned off, and the eleventh switch is turned off.

[0130] When the target operating frequency band is N78, control the first switch to be off, the second switch to be on, the third switch to be off, the fourth switch to be on, the fifth switch to be off, the sixth switch to be off, the seventh switch to be off, the eighth switch to be off, the ninth switch to be off, the tenth switch to be off, and the eleventh switch to be off.

[0131] In this embodiment, when the target operating frequency band is the mid-to-high frequency band or the N78 band, the third antenna radiator is in operation, while the first and second antenna radiators are not in operation and may generate interference signals. Controlling the first switch to open, the second switch to open, and the third switch to open eliminates the interference signal generated by the second antenna radiator. Controlling the fourth switch to open eliminates the interference signal generated by the first antenna radiator and provides electrical parasitics for the third antenna radiator. Controlling the sixth and seventh switches to open reduces the interference signal generated by the first antenna radiator and lowers the power consumption of the second tuning circuit. Controlling the fifth, eighth, ninth, tenth, and eleventh switches to open or close matches the mid-to-high frequency band or the N78 band. By controlling the corresponding switches in the tuning circuit to open or close, the interference signals generated by the first and second antenna radiators can be eliminated, thereby improving the performance of the antenna assembly.

[0132] For example, such as Figure 8-1 As shown, when the second antenna radiator is in operation, the antenna assembly's efficiency is -2.1 dB when the target operating frequency band is the L1 band of the Global Positioning System (GPS), -1.8 dB when the target operating frequency band is the 2.4 GHz band of Wi-Fi signals, and -2.3 dB when the target operating frequency band is the 5 GHz band of Wi-Fi signals. Here, S1 represents the radiation efficiency curve of the antenna assembly when the target operating frequency band is the L1 band of GPS or the 2.4 GHz band of Wi-Fi signals, and S2 represents the radiation efficiency curve of the antenna assembly when the target operating frequency band is the 5 GHz band of Wi-Fi signals. The vertical axis represents gain in dB, and the horizontal axis represents frequency in GHz.

[0133] For example, such as Figure 8-2As shown, when the first antenna radiator is in operation, the efficiency of the antenna assembly in the target operating frequency band (the receiving frequency band of the BeiDou satellite navigation system) is -1.4 dB. Here, S3 represents the radiation efficiency curve of the antenna assembly without switching losses when the target operating frequency band is the receiving frequency band of the BeiDou satellite navigation system; S4 represents the radiation efficiency curve of the antenna assembly including switching losses when the target operating frequency band is the receiving frequency band of the BeiDou satellite navigation system; S5 represents the total efficiency curve of the antenna assembly without switching losses when the target operating frequency band is the receiving frequency band of the BeiDou satellite navigation system; and S6 represents the total efficiency curve of the antenna assembly including switching losses when the target operating frequency band is the receiving frequency band of the BeiDou satellite navigation system. The vertical axis represents gain in dB, and the horizontal axis represents frequency in GHz.

[0134] For example, such as Figure 8-3 As shown, when the first antenna radiator is in operation, the efficiency of the antenna assembly in the target operating frequency band (the transmission frequency band of the BeiDou satellite navigation system) is -2.0 dB. Here, S7 represents the radiation efficiency curve of the antenna assembly without switching losses when the target operating frequency band is the transmission frequency band of the BeiDou satellite navigation system; S8 represents the radiation efficiency curve of the antenna assembly including switching losses when the target operating frequency band is the transmission frequency band of the BeiDou satellite navigation system; S9 represents the total efficiency curve of the antenna assembly without switching losses when the target operating frequency band is the transmission frequency band of the BeiDou satellite navigation system; and S10 represents the total efficiency curve of the antenna assembly including switching losses when the target operating frequency band is the transmission frequency band of the BeiDou satellite navigation system. The vertical axis represents gain in dB, and the horizontal axis represents frequency in GHz.

[0135] For example, such as Figure 8-4 As shown, with the third antenna radiator in operation, the antenna assembly efficiency is -1.7 dB in the mid-frequency band, -1.2 dB in the high-frequency band, and -1.5 dB in the N78 band. S11 represents the radiation efficiency curve of the antenna assembly when the target operating frequency band is B41, S12 represents the overall efficiency curve when the target operating frequency band is B1, S13 represents the overall efficiency curve when the target operating frequency band is N78, S14 represents the overall efficiency curve when the target operating frequency band is B40, and S15 represents the overall efficiency curve when the target operating frequency band is B41. The vertical axis represents gain in dB, and the horizontal axis represents frequency in GHz.
